Comment 2 for bug 1324685

The reason for the error message when using the regular way to install gems seems to be

% dir /var/lib/gems/1.9.1
insgesamt 4
drwxr-x--- 2 root root 4096 Mai 29 22:35 cache/

it's simply not readable for users other than root, thus forcing people to use the root account to proceed.

The file installed inside cache is

-rw-r----- 1 hadmut hadmut 120320 Mai 29 22:35 rake-10.0.4.gem

again with a permissions problem, which would be readable for the user only who ran bundle.

Wrong umask?
